Angular 2 到 4 - Rxjs Subject.d.ts 中的错误 [关闭]

Question

当我们启动多个项目时，ng2 中的 3 个和 ng4 中的 1 个，它们都独立工作。一个项目也使用 datatables.net。尝试将所有内容集成并升级到 ng4 时，出现此错误。

1. 登录是 1 个应用程序中的一个组件，而其他应用程序使用 login.html - 更好的方法是什么？

2. 编译错误

   “主题”类错误地扩展了基类“可观察”。 属性“电梯”的类型不兼容。 类型 '(operator: Operator) => Observable' 不可分配给类型 '(operator: Operator) => Observable'。 类型“Observable”不可分配给类型“Observable”。 类型“T”不能分配给类型“R”。

rxjs 是 5.4.2 版

已解决的版本 [rxjs 升级到 5.4.2 - 降级到 5.0.1] 提到应用程序运行后的详细问题是

Answer 1

TypeScript 升级时出现此错误。

您应该升级所有软件包。但可能有些包没有进行最后一次 TypeScript 修改。

然后您可以为这些项目做出贡献以使其兼容，或者您​​应该降级到支持 TypeScript 4.1 的最新 Angular 4 版本。
